Subject: 3.5' Drives (Again..)

Something I have noticed is that some modern PC drives do still have a
drive 0/1 selection. They're just not jumpers any more, rather they're
usually small soldered links or solder pads for SMT resistors.

As an example, I'm looking at three drives that fall to hand right now:

ALPS DF354H090F: small solder blob selects "DS1", would need removing
or cutting and "DS0" soldering.

Panasonic JU-257A606P: circuit board has positions for switches which
aren't fitted, so I'd presume that links could be fitted to the solder
pads. These switches include drive 0/1 selection, and also other
exciting things like a disk change/drive ready signal selector, which
is very handy if you want to hack a drive into an Amstrad with 3"
drives (e.g. PCW)

TEAC FD-235HF-B391-U5: a few soldered SMT links, including one for
DS0/DS1. Would need the link carefully moving across to the DS0
position.

I'm sure there are many other drives like these.
